Terminal Fire Damper
Introduction
The Installation, Operation and Maintenance manual applies to the terminal fire damper types CF1 - CF2, EI60S,
EI120S, contains basic information and recommendations regarding the design, installation and usage, which need to
be followed in order to guarantee a proper and trouble-free operation of the unit. The key to this is to read this manual
thoroughly, use the damper according to the instructions provided in it and to adhere to the safety requirements.

Warning
Some of the fire damper parts might have sharp edges - therefore it is necessary to use gloves during the installation
and usage of the damper.
In order to avoid electrical shock, fire or other damage that might occur as a result of incorrect usage and operation
of the unit, it is important to comply with the following principles:
• It is necessary to install the system according to the Installation manual.
• It is necessary to perform the fire damper check according to the manual.
Operation
General Information
The terminal fire dampers are defined as fire closures for ventilation ducts, to be installed in the spot where the
ventilation duct passes through the fire partition wall, or at the end of the duct in front of the outlet. In case of a fire
dampers work as a fire safety element and prevent the fire from spreading throughout the ventilation duct during a
specified amount of time.
• All the units are actuated by springs.
• Additional accessories, such as flexible couplings, disk valves etc., can be ordered separately.
• The accessories are supplied separately and demounted, ready to be mounted on site by the responsible staff.
The dampers are to be operated in a workplace which is protected from weather conditions and to be used in
ventilation ducts distributing the air without any other mechanic or chemical contamination in the following
operating conditions:
• The maximum air flow speed of 12 m/s.
• The maximum relative air humidity of 90%.
• The temperature falling within the range of -10 to +65°C.
In terms of noise, the fire dampers are passive. Increased noisiness only occurs while the damper is being opened or
closed as a result of inspection or fire, which should not last longer than 5 seconds.
As a standard, all the terminal fire dampers are equipped with a thermal fuse link, which, after having reached or
exceeded the temperature of 72°C with a ± 1,5°C tolerance, unblocks the actuating springs, which causes the damper
blades to close.
